Power Point

The purpose of this article is to extract the maximum power point at which the photovoltaic system can operate optimally. The system considered is simulated under different irradiations (between 200 W/m<sup>2</sup> and 1000 W/m<sup>2</sup>), it mainly includes the established models of solar PV and MPPT module, a DC/DC boost converter and a DC/AC converter. The most common MPPT techniques that will be studied are: "Perturbation and Observation" (P&amp;O) method, "Incremental Conductance" (INC) method, and "Fuzzy Logic" (FL) control. Simulation results obtained using MATLAB/Simulink are analyzed and compared to evaluate the performance of each of the three techniques.

This paper deals with the mitigation of voltage sag and harmonic profile improvement in a microgrid system. The microgrid system contains a hybrid combination of PV array, Battery interfaced with a cascaded multilevel inverter through a boost converter. The microgrid feeds a non-linear balanced load. The occurrence of voltage sag in the microgrid is compensated using the reference current for mitigation by using the SRF theory. The proposed power quality conditioner can compensate the voltage variations and harmonic profile distortions caused by the load changes. The efficacy of the proposed power quality conditioner in the microgrid system is validated through the MATLAB/Simulink.

ABSTRAKAplikasi dari inverter multilevel pada sistem Pusat Listrik Tenaga Surya (PLTS) dapat menghilangkan kebutuhan terhadap transformator, sehingga dapat mengurangi biaya investasi, mengurangi kompleksitas instalasi dan menghilangkan rugi-rugi daya transformator. Pada penelitian ini, sebuah inverter dengan topologi Cascaded H-Bridge Multilevel Inverter dirancang agar mampu mengubah tegangan rendah DC dari beberapa Photovoltaic (PV) array menjadi tegangan fasa-fasa 20 kV AC. Perancangan menghasilkan sebuah inverter 3 fasa 27-level dimana setiap level masing-masing memiliki PV array, DC-DC boost converter, H-bridge inverter, dan keluaran 3 fasa terhubung dengan filter LCL. Setiap komponen dari inverter dan sistem tersebut kemudian dimodelkan pada MATLAB Simulink untuk mensimulasikan kinerja dari setiap komponen dan sistem pada Standard Test Condition (STC) dari modul PV. Pada keadaan STC, daya 3 fasa maksimum yang dapat dihasilkan adalah 1,716 MW atau 68,54% dari daya DC maksimum sebesar 2,5 MWp. Sistem dapat menghasilkan tegangan fasa-fasa keluaran sebesar 20 kV dengan Total Harmonic Distortion (THD) di bawah 5%.Kata kunci: Pusat Listrik Tenaga Surya (PLTS), photovoltaic, Cascaded H-Bridge Multilevel InverterABSTRACTThe application of Multilevel Inverter in a Photovoltaic Solar Power Plant system could eliminate the needs of step-up transformer, which will reduce the system investment cost, simplify the system installation and also eliminate power losses of the transformer. In this paper, an inverter design was proposed with Cascaded H-Bridge Multilevel Inverter topology that is capable of converting low voltage DC power from several PV arrays into 20 kV AC power. The design resulted a 3 phase 27-level inverter where each level in the inverter has its own photovoltaic array, DC-DC boost converter, H-bridge inverter, and the 3 phase output is connected to LCL filter. Each component of the Inverter and the system were then modelled in MATLAB Simulink to simulate the operation of the components and the system at PV Standard Test Condition (STC). At STC, the maximum 3 phase output power of the system is 1,716 MW or 68,54% of maximum DC power of 2,5 MWp. The system can reach 20 kV of output voltage with less than 5% THD.

The main purpose of this paper is to model, simulate, and improve the performance of different 9 × 9 PV array configurations under different Partial Shading Conditions (PSCs) in order to extract the maximum power by defeat the mismatching power losses. Hence, PSCs reduces the performance of Photovoltaic (PV) arrays and increase the Local Maximum Power Points (LMPPs) on output characteristics P-V due to mismatching power losses between the PV panels. For this, Total-CrossTied (TCT) , and proposed Magic Square View (MSV) PV array topologies are considered for the study under Short Narrow shading patterns. PV array configurations enhancements and theirinvestigations are carried out with regard to the comparison of the Global peak of outlet power (GP).The parameters of the PV array configurations are performed in MATLAB/Simulink software.

In this paper, photovoltaic industry is introduced briefly. For the shortcomings of the fixed-step perturbation and observation (P&O) method in the maximum power point tracking (MPPT) technology, a variable-step P&O method is proposed and the algorithm is further improved. In the PV system, the MPPT is realized by changing the duty cycle of switching tube in the Boost converter. The simulations were conducted in the Matlab/Simulink platform. At last, the experimental results on the 3kw prototype showed that the new MPPT algorithm is effective.

This paper presents 200 KW three phase standalone photovoltaic systems supplying pumping station consist of four pumps 40 KW rating. The system utilizes a two stage energy conversion power conditioning unit topology composed of a DC-DC boost converter and three level-three phase voltage source inverter (VSI). The Boost converter in this paper is designed to operate in continuous mode and controlled for maximum power point tracking (MPPT). The fluctuating output power of the PV array system during the day is the commonly problem in the power system.  In this paper a nickel-Cadmium battery will be used to maintain the output power generated from the PV array supplying the pumps to be constant all the day under different operating conditions. The system is modeled and studied using MATLAB/Simulink
